Drum Beating

You play your drum, controlling the drum's roots to attack all targets within 20 ft. When you use this move, you can designate any number of creatures you can see to be unaffected by it. An affected creature's speed is halved in the area, and when the creature enters the area for the first time on a turn or starts its turn there, it must make a DEX save against your move DC. On a failed save, the creature takes 2d6 + MOVE grass damage. On a successful save, the creature takes half as much damage.

For the duration or until concentration is broken, your speed is reduced to 0.

At Higher Levels: The damage dice roll for this move changes to 2d8 at level 5, 4d6 at level 10, and 6d6 at level 17.
